EternaBond® lifting in places after installation.

The lifting problem is almost always an installation problem, and it is easily remedied. It usually occurs at a point where the EternaBond® was stretched over a protrusion like a trim strip or old sealant. Because EternaBond® is not a friction activated tape, stretching it to “fit” will decrease its normal adhesion abilities.

Because EternaBond® is pressure activated. Pressure is critical at all points on the tape, as it is being installed. Typical causes for lifting:

  • Tape not rubbed aggressively enough to activate the tape. This is particularly true around protrusions (trim strips, old sealant). ALL SURFACES THE TAPE COMES IN CONTACT WITH MUST BE RUBBED AGGRESSIVELY TO ACTIVATE!
  • Tape stretched over protrusions like trim strips, old sealant, etc.
When lifting occurs, the tape needs to be re-applied, using heat to reactivate it. This can best be accomplished by using a hair dryer or an iron. Other heat sources are not recommended.

  • When using a hair drier, put it on the hottest setting and heat up a small section at a time, allowing it to get almost hot and then rubbing it down.
  • When using an iron, lay a towel over the area where the iron will make contact. Use the iron on a cooler setting, and do NOT use the steam setting. Do a small section at a time and keep the iron moving. Regularly check the tape/roof surface temperature with your hand to make sure you do not overheat it. If it is too hot to touch, allow the area to cool down. Once the area is warm, rub or roll the EternaBond® aggressively to bond the tape to the roof.

If the EternaBond® is lifting in an area where it was stretched over a protrusion, cut the EternaBond® so it can be folded down and around the protrusion - like wrapping a package. Heat and rub the tape down. If desired, put another piece of EternaBond® over the folded area.

It is best if contact is 100%. When variations in the surface the EternaBond® is being applied to create an air bubble larger then the diameter of a quarter; or cause "tenting" to occur within 3/4" of the edge of the EternaBond®; or if a curve creates openings along the edge of the EternaBond®, we recommend the following.

Air Bubble: Lance, cut or pierce the bubble and squeeze the air out. The EternaBond® will seal the opening.

Tenting: Cut the tented area so the EternaBond® can be folded down flat. A Smaller piece of EternaBond® should then be used to seal the cut area.

Openings in the EternaBond® along the edge: This usually occurs when the EternaBond® is bunched together. 2 solutions for this situation:

  • Cut the bunched EternaBond® with a razor so it can be folded down, one side of the cut EternaBond® pressed against the surface, the other side folded over the first. A second, smaller piece of EternaBond® should then be used to seal the cut area.

  • Or press down the opening and seal the edge with a second piece of EternaBond®, or a good quality caulking, or sealant.

*Eterna-Tip: To keep clean the edge of the EternaBond® that will be facing into the wind, run a bead of caulking of sealant along that edge.
